Permanent Mold Casting

For higher volume orders we implement permanent mold tooling to combat
the price per part for aluminum castings. Given a large enough production
run permanent mold tooling can pay for itself and minimize lead times.
As opposed to packing sand around a pattern to create the cavity for the
part, a piece of iron is milled to the appropriate geometry to produce
the mold. Once the mold is produced it can be indexed into a vault and
pulled anytime the part needs to be run. Whenever possible multiple cavities
are machined into a single mold to maximize the number of parts per pour.
A single permanent mold can yield thousands of parts and can do so with
great consistency. The surface finish and tolerance is comparable to that
of die casting.
